Dietary habits and vitamin intake impact brain health and dementia risk

Dietary habits and nutritional intake play significant roles in long-term brain health and the risk of developing dementia. Excessive consumption of carbohydrates can lead to blood sugar spikes, which strain cerebral blood vessels. High intake of fructose, often found in processed foods and soft drinks, is specifically linked to insulin resistance, a factor associated with Alzheimer's disease.

Furthermore, high levels of saturated and trans fats contribute to arterial stiffness and chronic inflammation, both of which can accelerate the death of nerve cells. Excessive salt intake can lead to hypertension, further damaging the blood vessels in the brain.

Regarding micronutrients, deficiencies in vitamins C, D, and E can impact bodily functions and aging processes. While vitamins are essential for immune support, bone health, and antioxidant protection, excessive supplementation is not always beneficial. For instance, long-term high doses of vitamin C may increase the risk of kidney stones, and excessive vitamin D supplementation in healthy adults offers limited additional benefits for preventing lifestyle diseases. Maintaining a balanced diet with colorful vegetables, fish, and nuts is recommended to meet daily requirements.
